Description
Technical Field
[0001] This utility model belongs to the field of cooling technology for coal gangue piles, specifically relating to a heat pipe arrangement rack for cooling coal gangue piles. Background Technology
[0002] As solid waste accumulations generated during coal mining, gangue piles contain combustibles such as residual coal and carbonaceous shale that are prone to slow oxidation reactions under the influence of oxygen and moisture, releasing a large amount of heat. If this heat cannot be dissipated in time, it can easily lead to spontaneous combustion accidents. Therefore, efficient cooling of gangue piles and suppression of spontaneous combustion have become one of the core tasks of ecological governance and safe production in the coal industry. Among the many gangue pile cooling technologies, heat pipe cooling technology is widely used for heat removal from the inside of gangue piles due to its advantages such as high heat transfer efficiency, low energy consumption, and stable operation.
[0003] In areas where coal gangue settlement is severe, the heat pipe installation area often sinks due to the compaction of the accumulated material under its own weight, softening by rainwater infiltration, and internal heat effects. Therefore, a coal gangue cooling heat pipe layout rack is needed to stabilize and fix the cooling heat pipes in the area, restricting the heat pipes from settling and ensuring that the heat pipes are in an effective heat dissipation position. In existing technologies, a concrete base is typically pre-cast on the surface of the waste rock pile. Fixing holes are made in the base, and after the heat pipe is inserted into the fixing holes, bolts are used to drive arc-shaped clamps to clamp and fix the heat pipe from both sides. In practice, an independent base must first be poured according to the installation position of each heat pipe, and then the bolts are adjusted one by one to make the clamps tighten the heat pipe. If the spacing or angle of the heat pipe needs to be adjusted, the base must be removed and reconstructed. Other fixing devices adopt a rigid bracket structure, with fixed-interval mounting slots on the bracket, which are fixed by engaging with the outer wall of the heat pipe through the slots; However, in actual waste rock cooling projects, the aforementioned existing devices have obvious defects: Poor adaptability: Existing fixing devices are mostly customized designs, which can only be adapted to heat pipe mounting holes with specific spacing and angles. When avoiding local relaxation areas in the same project, the actual parameters of two adjacent heat pipe mounting holes often show irregular deviations. For example, adjacent holes with a design spacing of 200mm become 180mm to avoid the relaxation area on the left, and become 220mm to avoid the hole on the right. Adjacent holes with a design tilt of 15° are adjusted to 12° and 20° respectively to avoid different relaxation areas. Customized devices cannot adapt to this situation. If they are forcibly installed according to fixed parameters, either the clamp cannot fit the heat pipe due to mismatched spacing, or the heat pipe will be deformed due to stress due to angle deviation. If a new base is customized for each hole, not only will the construction cost increase dramatically, but the construction of the base will also damage the surrounding gangue structure and exacerbate the instability of the relaxation area. It cannot meet the needs of existing gangue mountain transformation and complex construction scenarios. Summary of the Invention
[0004] The purpose of this utility model is to provide a heat pipe arrangement frame for cooling in coal gangue mountains, which can easily adapt to heat pipe installation holes with different design spacings, and can also be adapted to installation holes with different angles. When fixing, it can achieve one-time clamping and fixing of multiple cooling heat pipes, improving the convenience and efficiency of operation.
[0005] The specific technical solution adopted by this utility model is as follows: A heat pipe arrangement frame for cooling coal gangue piles includes an installation frame. An adjusting bolt is threaded onto one side of the installation frame. One end of the adjusting bolt is rotatably connected to a rectangular plate that is slidably connected to the installation frame. Multiple dovetail sliders are slidably connected to one side of the rectangular plate. A first circular cylinder is rotatably connected to one side of the dovetail sliders. A first arc-shaped clamping plate is fixed to one end of the first circular cylinder. A guide plate is fixed to the inner side of the installation frame. A rectangular limiting block, the same number as the dovetail sliders, is slidably connected to the outer side of the guide plate. A second circular cylinder is rotatably connected to the side of the rectangular limiting block closest to the first arc-shaped clamping plate. A second arc-shaped clamping block, adapted to the first arc-shaped clamping plate, is fixed to one end of the second circular cylinder.
[0006] A second U-shaped positioning plate is fixed to the outer side of the second circular cylinder, and a first U-shaped positioning plate is fixed to the outer side of the first circular cylinder. The second U-shaped positioning plate is slidably connected to the first U-shaped positioning plate.
[0007] The mounting frame has a movable groove. The end of the second circular cylinder away from the second arc-shaped clamping block extends into the movable groove. An L-shaped mounting bracket is fixed to the top of the rectangular limiting block. A positioning bolt is threaded to the top of the L-shaped mounting bracket. An elastic positioning plate that is slidably connected to the bottom of the positioning bolt is rotatably connected to the L-shaped mounting bracket. An arc-shaped positioning plate is fixed to the bottom of the elastic positioning plate and inside the movable groove. The elastic positioning plate abuts against the top of the mounting frame, and the arc-shaped positioning plate abuts against the outer side of the second circular cylinder.
[0008] The technical effects achieved by this utility model are as follows: This invention not only easily adapts to heat pipe mounting holes with different design spacings, but also precisely adjusts the clamping angle of the first arc-shaped clamping plate and the second arc-shaped clamping block to fit mounting holes with different angles. Furthermore, it can clamp and fix multiple cooling heat pipes at once during fixing, improving operational convenience and efficiency. Attached Figure Description

[0011] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0012] like Figure 1-5 As shown, a heat pipe arrangement frame for cooling a gangue pile includes a hollow mounting frame 1. Anchor rods 19 are fixed at the four corners of the bottom of the mounting frame 1. The anchor rods 19 can be driven into the rock strata or stable area inside the gangue pile to provide a fixed support point for the entire device. One side of the mounting frame 1 is threaded with an adjusting bolt 2. One end of the adjusting bolt 2 extends to the inside of the mounting frame 1. One end of the adjusting bolt 2 is rotatably connected to a rectangular plate 3. Both ends of the rectangular plate 3 abut against the mounting frame 1. When the adjusting bolt 2 rotates, the rectangular plate 3 abuts against the mounting frame 1, and the rotation of the rectangular plate 3 drives the rectangular plate 3 to move. See attached document Figure 2 , 3 and attached Figure 4 A dovetail groove is provided on the side of the rectangular plate 3 near the inner side of the mounting frame 1. A dovetail slider 20 is installed on the inner side of the dovetail groove on the rectangular plate 3. The dovetail slider 20 and the rectangular plate 3 are slidably connected through the dovetail groove, and the dovetail slider 20 and the dovetail groove on the rectangular plate 3 are provided with an interference fit. Guide rods 18 are provided at both ends of the rectangular plate 3. Guide holes with diameters matching the guide rods 18 are opened at both ends of the rectangular plate 3. The guide rods 18 slide through the guide holes and are slidably connected to the rectangular plate 3. The guide rods 18 are fixed at both ends of the inner side of the mounting frame 1. When the rotating adjusting bolt 2 drives the rectangular plate 3 to move towards the second arc-shaped clamping block 9, the guide rod 18 passes through the guide hole through the rectangular plate 3, restricting the rectangular plate 3 to move only along the axis of the guide rod 18. This prevents the rectangular plate 3 from shifting laterally or rotating due to uneven force, such as vibration of a rock pile or deviation of the thread transmission of the adjusting bolt 2. In addition, it enhances the bending and deformation resistance of the rectangular plate 3, preventing the rectangular plate 3 from sagging in the middle or tilting on the side due to excessive force. One side of the dovetail slider 20 is rotatably connected to a first circular cylinder 5, and one end of the first circular cylinder 5 is fixed with a first arc-shaped clamping plate 6. A guide plate 11 is fixed on the inner side of the mounting frame 1. A rectangular limiting block 10 with the same number as the dovetail slider 20 is provided on the outer side of the guide plate 11. A limiting groove adapted to the rectangular limiting block 10 is opened on the inner side of the rectangular limiting block 10. The guide plate 11 passes through the inner side of the limiting groove of the rectangular limiting block 10. The rectangular limiting block 10 and the guide plate 11 are slidably connected through the limiting groove. A second circular cylinder 8 is rotatably connected to the side of the rectangular limiting block 10 near the first arc-shaped clamping plate 6, and a second arc-shaped clamping block 9 adapted to the first arc-shaped clamping plate 6 is fixed at one end of the second circular cylinder 8. When in use: First, based on the specific distribution of the installation holes of the cooling heat pipe in the gangue mountain, accurately determine the installation coordinates of the installation frame 1, fix the anchor rod 19 in the stable rock layer or compacted gangue layer inside the gangue mountain, and fix the installation frame 1 firmly through the anchoring effect of the anchor rod 19 and the gangue layer. Push the second arc-shaped clamping block 9 and the first arc-shaped clamping plate 6, adjust the spacing between multiple second arc-shaped clamping blocks 9 and the spacing between multiple first arc-shaped clamping plates 6 to adapt to the spacing of different cooling heat pipe mounting holes, and ensure that the combination of each second arc-shaped clamping block 9 and the corresponding first arc-shaped clamping plate 6 can be accurately aligned with the corresponding mounting hole; By moving the second arc-shaped clamping block 9 and the first arc-shaped clamping plate 6, the clamping angle of the second arc-shaped clamping block 9 and the first arc-shaped clamping plate 6 can be independently adjusted, so as to accurately adapt to the cooling heat pipe mounting holes with different tilt angles. After adjusting the spacing and angle, slowly insert the cooling heat pipe between the corresponding second arc-shaped clamping block 9 and the first arc-shaped clamping plate 6 in each group, so that the heat pipe falls into the hole along the axis of the mounting hole until the bottom of the heat pipe reaches the preset depth. At this time, the outer wall of the heat pipe and the inner wall of the second arc-shaped clamping block 9 are initially in contact. Use a wrench or your hands to rotate the adjusting bolt 2 clockwise. Rotating the adjusting bolt 2 will move the rectangular plate 3 horizontally towards the second arc-shaped clamping block 9, thereby moving the first arc-shaped clamping plate 6 closer to the second arc-shaped clamping block 9. Finally, the cooling heat pipe is stably clamped between the second arc-shaped clamping block 9 and the first arc-shaped clamping plate 6, reducing the risk of the heat pipe sinking due to the loosening of the gangue. See attached document Figure 4 and attached Figure 5 Both the first arc-shaped clamping plate 6 and the second arc-shaped clamping block 9 are fixed with elastic clamping plates 16. When the cooling heat pipe is clamped, the two elastic clamping plates 16 will deform uniformly due to the pressure of the outer wall of the cooling heat pipe. The deformation fills the gap between the heat pipe and the clamping plate, increases the contact area and friction, improves the clamping stability, and buffers the clamping force with their own elasticity to avoid the rigid contact causing indentations or scratches on the outer wall of the heat pipe, thus protecting the integrity of the heat pipe structure. See attached document Figure 3 , 4 and attached Figure 5 To further improve the stability of the cooling heat pipe, a movable groove 23 is provided on the mounting frame 1. One end of the second circular cylinder 8 away from the second arc-shaped clamping block 9 passes through the interior of the rectangular limiting block 10 and extends to the inside of the movable groove 23. An L-shaped mounting bracket 12 is fixed to the top of the rectangular limiting block 10. A positioning bolt 13 is threaded to the top of the L-shaped mounting bracket 12. An elastic positioning plate 15 is rotatably connected to the bottom of the positioning bolt 13. One end of the elastic positioning plate 15 abuts against the L-shaped mounting bracket 12. An arc-shaped positioning plate 14 is fixed to the bottom of the elastic positioning plate 15 and located inside the movable groove 23. In use: After the cooling heat pipe has been initially clamped and fixed by the first arc-shaped clamping plate 6 and the second arc-shaped clamping block 9, use a wrench or your bare hand to rotate the positioning bolt 13 clockwise. The rotation of the positioning bolt 13 causes the elastic positioning plate 15 to move toward the mounting frame 1. During the downward movement of the elastic positioning plate 15, the bottom of the elastic positioning plate 15 abuts against the top of the mounting frame 1, thereby locking the spacing of the rectangular limit block 10 and preventing the heat pipe spacing from shifting due to non-human factors. At the same time, the arc-shaped positioning plate 14 at the bottom of the elastic positioning plate 15 will move down with the elastic positioning plate 15. When the bottom of the elastic positioning plate 15 abuts against the top of the mounting frame 1, the arc-shaped positioning plate 14 abuts against the second circular cylinder 8, thereby locking the angle of the second circular cylinder 8 and avoiding the heat pipe clamping angle deviation caused by non-human factors. In addition, elastic pads 24 are installed on the arc-shaped positioning plate 14 and the elastic positioning plate 15, and grooves 21 are provided on the second circular column 8. Anti-slip strips 22 are provided on the mounting frame 1 in the area of the elastic pads 24 on the elastic positioning plate 15. As the elastic positioning plate 15 moves down, the elastic pad 24 on the inner side of the arc-shaped positioning plate 14 first contacts the outer wall of the second circular cylinder 8. At this time, the positioning bolt 13 continues to rotate and generates downward pressure, forcing the elastic pad 24 to be squeezed and deformed. Since the second circular cylinder 8 is provided with a groove 21, the deformed elastic pad 24 will naturally embed into the groove 21 to form an interlocking structure. Through the elastic interlocking of the elastic pad 24, the friction force increases significantly, hindering the rotation of the second circular cylinder 8, further reducing the risk of non-human rotation, and improving the angle locking stability of the second circular cylinder 8. While the arc-shaped positioning plate 14 engages with the second circular cylinder 8, the elastic pad 24 at the bottom of the elastic positioning plate 15 contacts the anti-slip strip 22 at the top of the mounting frame 1. The continuous downward pressure causes the elastic pad 24 to fit tightly against the surface of the anti-slip strip 22. The elastic pad 24 and the anti-slip strip 22 fill the tiny gap between the elastic positioning plate 15 and the mounting frame 1, ensuring full contact. The elastic pad 24 and the anti-slip strip 22 increase the static friction, further reducing the risk of non-human rotation and improving the locking stability of the rectangular limit block 10. See attached document Figure 3 , 4 and attached Figure 5 To further improve the ease of operation, a second U-shaped positioning plate 7 is fixed to the outside of the second circular cylinder 8, and a first U-shaped positioning plate 4 is fixed to the outside of the first circular cylinder 5. The second U-shaped positioning plate 7 is slidably connected to the first U-shaped positioning plate 4. When it is necessary to adjust the angle of the first arc-shaped clamping plate 6 and the second arc-shaped clamping block 9 to adapt to the installation holes of cooling heat pipes with different tilt angles, simply move the first U-shaped positioning plate 4 or the first circular cylinder 5. Through the sliding relationship between the first U-shaped positioning plate 4 and the second U-shaped positioning plate 7, the first arc-shaped clamping plate 6 and the second arc-shaped clamping block 9 can be driven to rotate, thereby facilitating the adjustment of the angle. When faced with different spacing between the mounting holes of different cooling heat pipes, push the first U-shaped positioning plate 4 or the second U-shaped positioning plate 7 to conveniently adjust the spacing between multiple first arc-shaped clamping plates 6 and the spacing between multiple second arc-shaped clamping blocks 9, adapt to different mounting hole spacing requirements, and reduce the difficulty of operation when adjusting the spacing. See attached document Figure 1The top of the mounting frame 1 is fitted with a protective cover 17, which is made of elastic material. The protective cover 17 covers the outside of components such as adjusting bolt 2, positioning bolt 13, guide plate 11, and rectangular limit block 10. It can prevent dust and gangue debris in the gangue mountain environment from entering the gaps between the components, such as the threads of the adjusting bolt 2 and the mounting frame 1, and the sliding grooves of the rectangular limit block 10 and the guide plate 11, to avoid the components getting stuck. At the same time, the elastic material can absorb the impact when small gangue rolls down, protect the internal components from collision damage, and extend the service life of the device. A protective sleeve 25 is installed on the outside of the mounting frame 1 and on the outside of the adjusting bolt 2. When the adjusting bolt 2 is rotated into place, the protective sleeve 25 tightly wraps the exposed part of the adjusting bolt 2 through elastic deformation, preventing rainwater and dust from entering the thread gap between the adjusting bolt 2 and the mounting frame 1, and avoiding thread corrosion. Meanwhile, the friction between the protective sleeve 25 and the adjusting bolt 2 can limit the non-human rotation of the adjusting bolt 2, such as loosening caused by vibration, and further ensure the clamping stability. In summary, this utility model not only easily adapts to heat pipe mounting holes with different design spacings, but also precisely adjusts the clamping angles of the first arc-shaped clamping plate 6 and the second arc-shaped clamping block 9 to fit mounting holes with different angles. Furthermore, it can achieve one-time clamping and fixing of multiple cooling heat pipes during fixing, thus improving operational convenience and efficiency.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
